Abstract

L'invention concerne un dispositif de suralimentation (4), en particulier un turbocompresseur à gaz d'échappement, présentant un dispositif de commande (1) servant à actionner un dispositif de réglage, en particulier d'une géométrie de turbine variable ou d'une soupape de décharge, le dispositif de commande (1) étant accouplé au dispositif de réglage par l'intermédiaire d'une bielle de commande (2). Selon l'invention, le dispositif de commande (1) comporte au moins une butée minimale interne (5) qui limite le déplacement de la bielle de commande (2). Cela permet un préréglage et ainsi un montage ou remplacement plus simple du dispositif de commande (1).
